Hi Veronica,
How can I try MOTreeMapLayout? I only found a test but not an official example. In one of my trees I just changed the layout to use this one. But when drawing there is an error because a point has a fraction as one of its coordinates (integer@fraction).
I fixed MOTreeMapLayout and added a test. However, I am not sure the result is what one would expect. Here is the screenshot:
If having a tree map layout is important for you, than I will work on it with a student in December. Let me know.
Cheers, Alexandre
